jquery - 如何使用轮播关闭 X 上的 Bootstrap 4 弹出窗口

问题描述

当有人单击 X 图标时，我试图关闭 Bootstrap 4 弹出窗口。

如果我删除代码 'data-backdrop="static" 它会在我单击模式外的任何位置时关闭弹出窗口。但是，这不会起作用，因为每次有人尝试单击轮播的下一个图标时，它都会自动关闭弹出窗口。我只想在有人仅单击 X 图标时关闭弹出窗口。

解决方案

您应该链接到正确的CSS 和 JavaScript 文件；对于 Bootstrap 4（撰写本文时的当前版本是 4.3.1）：

关闭按钮的属性值data-dismiss也应该设置为modal：

<button type="button" class="close" data-dismiss="modal">&times;</button>

关闭按钮和轮播也应该放在里面.modal-content——你可以使用自定义 CSS 使模式透明。

工作示例

/* Automatically open the modal */
$('#myModal').modal('show');
/* Make the modal be transparent */
#myModal .modal-content {
  background-color: transparent;
  border: 0;
}
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" />

<div id="myModal" class="modal fade" role="dialog" data-backdrop="static">
  <div class="modal-dialog">
    <div class="modal-content">
      <!-- Button to close the modal -->
      <div><button type="button" class="close" data-dismiss="modal">&times;</button></div>

      <!-- Carousel -->
      <div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
        <div class="carousel-inner">
          <div class="carousel-item active">
            <img class="d-block w-100" src="https://placeimg.com/550/250/nature" alt="First slide">
          </div>
          <div class="carousel-item">
            <img class="d-block w-100" src="https://placeimg.com/550/250/any" alt="Second slide">
          </div>
        </div>
        <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
          <span class="carousel-control-prev-icon" aria-hidden="true"></span>
          <span class="sr-only">Previous</span>
        </a>
        <a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next">
          <span class="carousel-control-next-icon" aria-hidden="true"></span>
          <span class="sr-only">Next</span>
        </a>
      </div>
    </div>
  </div>
</div>
